From 2806ccd7ad9073f4f1a065b5672d7592e7838e97 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 19 Dec 2006 02:12:42 +0100 Subject: [PATCH] [MIPS] Delete duplicate call to load_irq_save. This call may have resulted to local_tlb_flush_range returning with interrupts disabled resulting in excessive interrupt latency.
